Thin, baked chips have irregular shapes and surface bubbles produced by cutting a fermented, wheat-based, compressed dough sheet into pieces with different shapes and notches with a single rotary cutter. The dough pieces form an interlocking pattern, and the notches extend around the periphery of each piece. The notches are spaced around the periphery of each piece and facilitate separation of the dough pieces from each other while substantially avoiding tearing and breaking of the dough pieces. Notches of each piece are aligned or contiguous with notches of any adjacent piece in the interlocking pattern.
